lle it known that l, lanzor Fl. llu l l lNG'H )N, a citizen of the llnited States, residing at lrlinneapolis, in the county ol lllennepinand tltati-a ol hfinncsota, have invented certain new and usefullmprovemcnts in Acetylene "llas lleneralms; and l do hereby declare thefollowing to be a lull, clear, and exact description ol. the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

lily present invention relates to acetylcnegas generators, and has l'orits object to improve thesame in theseveral partlcularshereinal'ternoted.

To the above ends the invention consists of the novel devices andcombinations of devices heri-iinal'ter described, and delineiil in theclaim.

The invention is illustrated in the accompanying drawings, wherein likecharmzters indicate like parts throughout the several views.

l igu re 1 is a view, princi mlly in vertical section, but with someparts shown in side elevation and some parts broken a ay, illustratingmy invention applied to a lamp of the type generallydesign ate/d asstudents lam Fi 2 is a horizontal section on the line 0i 1* 1g. 1; andlb 1g. 3 1s a detail m a vertical section, showing the nozzle ol thewater-delivery tube sectioned on the same line as Fig. 1.

The numeral 1 indicates the rod ol the lam p-supporting stan d thenumeral 2 the gasburner, the numeral 3 the sleeve mounted to slide onthe rod 1, and the-numeral l the collar working on the rod 1 andprovided with a set-screw 5, holding it wherever set. The collar 4:supports the sleeve 3, and the said sleeve is rigidly attached at twopoints to a vertically-disposed cylindrical case (S. The

stem of the burner 2 has an enlargement 2*, which surrounds the sleeve 3and opens into the gascon( luits 7, formed on the l')()l1l'/UIH ol thecylii'uler 6. ward From the receiving end of 7 through the cylinder (3at one A gastnbe 8 extends upthe conduit side thereot and terminates inacontracted nozzle a; A plug 0 in the bottom ol the cylinder (3 whenremoved permits the conduit 7 to be drained el" any condensed waterwhich may have accumulated therein.

An auxiliary waterawhaml)cr ll) telescopes into the upper end of thecylindrical shell (l and is provided with a bottom 11, locatedaboveitslmveredge. 'llmbottom l is termed with a depending neck orsleeve-like waterpassage 12, which is normally open, but is adapted tobe closed by a valve Iil when the said auxiliary waler-chambcr it) israised vertically l'rom working position. This valve 13 has stems ll,that work telescopuially in guide-sleeves 15, secured to the top ot thechamber 10. Said valve 12-} is l'urther pro vided with a (ilepending loot Hi, that engages with :1. lug I? on the interior ol' the shell (3and holds the said valve open when the resm'voir or chamber 10 is inworking position.

, Rigidlysecin'ed to the bottom I 1 ol' the reservoir H) by llanges 18is a depending cylindrical gcnerating-chamber '19, which is bulged atone side, as shown at 20, to all'ord a passage tor the gas tube 8. Agas-dclivery 7 5 tube Z'l leads upward lrom the top of the gen eratiligchamber 19 through the ater-resin voir l0 and is pr vided with adownturned branch 22, which telescopesever the upperend of the gas-tube8 and unites with the bulged 8o portion 20 ol" the generating-chamber.'lhe depending peripheral llange ol the reservoir 10, just below thebottom I l, is lormed with air-passages 23, which admit air into theprimarywater-compartment termed within the shell 6. l t will beunderstood that there will be leakage ol air between the telescopingparts 01' the shell 6 and reservoir 10.

The carbid-holder is provided by a cylindrical cup 24, having atelescopica]ly-rcmovo able top 25,1'ormed with gas-escape passages 26and with a centrallylepending sleeve 27. The cap 24 has one or morespring-lingers 24 that l'rictiomllly engage the walls of the chamber '19to hold said cap in working posi- 5 tion against the action of gravity.A waterdistribution pipe or tube 28 opens through the bottom of the cup2 and extends vertically upward on the axis thereol and telescopes intothe sleeve 27. The lower end ol said tube 28 is open and prel'erahly ishellmouthed, as shown at 20. The bottom ot the cup 24: is shown asprovided with a hub portion 30, with which the tube 28 has scre\\'threade l engagement. The upper end of the tube 28 terminates in nozzlehaving a contracted passage 3 l and a larger passage leading thereto andinto which is mounted with screw-threaded engagement, a conical pointed.valve 32, having a longitudinal pas- 33. By adjustments of the valve 32the contracted passage 31 may be opened more or less, so as to give arestricted passage ol the exact desired water-conducting capacity.Preferably a nozzle-cap 34, having perforations 35, is screwed onto theextreme upper end of the tube 2%. A perforate tube 36 is placed axiallywithin the cup 24., surrounding the sleeve 27 and telescoping at itslower end over the hub 30. This perforate tube 36 holds the carbid 2within the generatingchamber out of contact with the sleeve 27 and tube28, and thus prevents the waterdelivery passages 'lrom becoming cloggedby the carbid residue.

The generating-chainher or cup 24; and parts attached thereto are ofcourse removed l rom working positions with the auxiliary waterchan'iber r reservoir l and while they are removed the shell is partlytilled with water, (indicated by g in I.) This water when the removableparts are again placed in working position will rise around thegeneratingcliamber if), substantially as indicated in Fig 1, and it willalso rise within the water-tube 2H and will overflow through thewater-passages 33, 31 and 35, and lrom thence will run down the orderside of said tube 28 and through the perhvrations ol the perl'oratesleeve 36 into contact with the carbidi llhenevtnr the g :-pres surewithin the generating-ehambei exceeds the pressure ol' the teed-water,it. will of course drive downward the column ol water in the tube 2S andtemper generation el gas. The gas gene-rat d passes first u nvardthrough the perforations 26.

thence tlll 'flll ljl'l. the tubes 21 and 22, thence through thecontracted nozzle U" and tube 8 into the conduit 7, and lrom thencethrough the stem of" the burner to the burner proper. The burner Zprovided with a valve 2'. The gimerating action is started by openingthe valve 2" so as to reduce the s-pressure within thegenerating-ehamber, and the generating action is stopped by closing saidvalve so as to permit an increase o'l' pressure in saidgeneratirig-chamber.

The auxiliary reservoir or chamber is of course filled while it isremoved from working position and turned upside do n, so as to cause thevalve 155 to open up the passage 12. When the said auxiliary reservoiris in working position, as shown in Fig. l, water will be suppliedtherefrom to the prin'iary water chamber whenever the water in the l- "tr is hovered so as to open the lower end of the sleeve or passage 12.

From the foregoing description and statemen made it will be understoodthat the devices described are capable of modification within the scopeof my invention as herein. set lorth and claimed.

that I claim, and desire to secure by Letters Patent of the UnitedStates, is follows:

In a generator of the character described, the ;-,oinbination. with ashell ad apted to contain water, of an auxiliary waterreservoir fittingthe upper end of said shell and com munieatii'ig therewith through itsbottom, a generating cham-her secured to the bottom o'l said auxiliaryreservoir and normally submerged in tl' e water cortz'tined in saidshell, :1 carbid-holder reinovably held within said.generating-chamlier, a water-siu ply tube opening through the bottom olsaid carbidholder from the lower portion of said shell, as-outlet tubel'ormed ol telescoping sections, one section ol' which secured to saidshell and the other to said auxiliary ressuhstan ervoir and eneratingchamber, tially deieribed.
